variables from html form not passing

Anon

For some reason, the php pages that are recieving variables from my html forms are not working correctly. Even this simple example is not working correctly:

<body>
<form>
name:
<input type=text name="username">
<input type=submit value="Submit">
</form>
<br><br>
your name:

<?php
echo($username);

?>
</body>

I get the expected 'undefined variable' warning, but even after i enter something into the field and click submit, it still gives me the warning, and does not display the name. Did I miss some kind of setting in an .ini file or something?
I'm running PHP4.2.1 on Apache1.3.24 on Win2k.

Thanks a lot in advance.

<?php
echo $_GET['username'];
?>

or

<?php
echo $_POST['username'];
?>

depending on your form. See:

Hello Adam,

since PHP 4.1.0 the default value for register globals is off.

That means that variables which come to the script from an other site are not set.

Therefore you must declare them per hand. All register variables are in the arrays $GET, $POST, and so on.

You must do the following:

$username = $GLOBALS["username"]; before using the variable username.

or do
$username = $HTTP_GET(or POST)VARS[username]
